hypersensitivity Flashcards
4 types of hypersensitive
1 - anaphylaxis
2 - myasthenia gravis
3 - rheumatoid arth.
4 - metal hypersensitivty
which ones are adaptive immunity
1,2,3
which ones are innate immunity
4
an excessive immune response can be categorized as?
ACID
alergic, cytotoxic, immune complex, delayed
anaphylaxis results
decrease BP, airway obstruction, hypoxia
risk factors anaphylaxis
asthma
acute infection
patho of anaphylaxis
large amounts of chemical mediators are released from mast cells resulting in
vasodilation, edema in lungs
three criteria for diagnosing anaphylaxis
1 - acute, skin, mucas, respiratory or BP effected
2- two of: skin/music, response, gastintestional pain
3- rescued BP, known alergen
epinephrine effect
inc BP, RR, HR
vasoconstriciton
antihistamine effect
block mast cell activity
glucocorticoids. mech n effect
anti inflamm
slower action
intravenous fluid mech n effect
direct
Incase BP quick
myasthenia gravis
acquired autominnue deficit of ACH
fatigued
risk factors myasthenia
viral infection
patho myasthenia
mm cell death
signs sytoms myasthenia
fatigue double vision
class of myasthenia
1 - eye mm weak 2- eye mm n some other mm 3- eye, mod mm weakness 4- eye, sever mm weakness 5- intubate the airway
treat myasthenia
anti Actyl drugs
corticosteroids
role of PT myasthenia
educate
strength
assit in resp complication
two types arthritis
inflammatory
non inflam
inflam artris
RA most common
non inflam
OA most common
RA defined
three or more joints
symptoms more tan 6 weeks
patho RA
auto immune
RA can lead to
atherosclerosis so manage cardio risk factors
PT RA
exercise, pain, strength
